rustc 1.23.0 panic on windows

[saarw]

Getting the following compiler panic in 1.23.0 stable on windows (and only on Windows, runs fine on Mac and Linux). Don't have direct access to the machine so can't get backtrace or try nightly on it right now, but may try later.

error: internal compiler error: unexpected panic

note: the compiler unexpectedly panicked. this is a bug.

note: we would appreciate a bug report: https://github.com/rust-lang/rust/blob/master/CONTRIBUTING.md#bug-reports

note: rustc 1.23.0 (766bd11 2018-01-01) running on x86_64-pc-windows-msvc

thread 'rustc' panicked at 'specified instant was later than self', src\libcore\option.rs:874:4
note: Run with RUST_BACKTRACE=1 for a backtrace.

error: Could not compile ordered-float.

I cannot reproduce with ordered-float:

It seems to happen in different crates. now got it with error: Could not compile num-traits.

What is your precise version of Windows and what is the exact CPU model you are using? This sounds very much like a system bug in that QueryPerformanceCounter is not returning a monotonic result.

Restarting the machine got the builds working again, so can no longer reproduce it.

[retep998]

What was the uptime of the machine last time? It's possible that bug only manifests when the system timer gets high enough.
